Drinking orange juice every day could help improve the brain power of elderly people, researchers claim, the Daily Mail reports. And it takes less than two months to show marked improvements in memory, speech and reaction times, according to a study. Scientists think the results are down to chemicals called flavonoids - a natural substance which occurs in high levels in oranges. Research has suggested that flavonoids may improve memory through the activation of signalling pathways in the hippocampus, a part of the brain that is associated with learning and storing information.
